I had them on a Falcon Controller, right now they are running with a msc on each arch. You could hook two together for a total of 96 nodes on one controller, but I have kept them separate. I have excess hubs, SSCs, mSC, etc. I play with them all. I have a lot of stuff as backups for my show equipment which give me lots to play with if I want to try something new. The arches used inexpensive material and I had nodes available so it has worked out good. The only critical item that is not backed up is my FM transmitter. I keep looking at getting another one, but so far have not seen one that I like enough to order.
